Looking at your reviews you have probably been threatened with suspension because three of your listings have received ratings of 4.6 - which Airbnb sees as below the quality it expects for listings on its platforms ie your listings have probably been flagged for a lack of positive review ratings . @Seokhwan0
You should have received notifications from Airbnb when you had lower reviews asking you to address issues .
a quick look at your listings with lower reviews show guests have been complaining of listings not being clean particularly in communal areas, noise issues and insects .
